SnapCenter 6.0 - proxy issue

[kombayn]

Hello

I've upgraded SnapCenter from version 5.0 to 6.0 and since upgrade ALL jobs are failing with below error:

Error: The proxy tunnel request to proxy 'http://x.x.x.x:3128/' failed with status code '403'."

The fun fact is that I've never used proxy for SnapCenter and I've even noticed that I have the same proxy error for migrating SnapCenter  repository backup schedule which is local on SnapCenter host:

I've tried to search where could the proxy settings be configured - in the appsettings.json  there is nothing - I only found this:
"ProxyTo": ""

Does anyone knows where the proxy settings could be located? And why they changed after upgrade?

Hello,

Have you try the 6.0P1 version ?

And have you IPv6 enable on your SnapCneter ? if yes try to disable it

Hello. From what I can see on support site there is no P1 version available yet for SnapCenter server - only vSphere plugin has P1. I've disabled IPv6 and rebooted the host but it didn't resolve the issue.
